SPECIFICATION forming part of Letters Patent N 0. 644,935, dated March 6, 1900.

in the county of Columbia and State of Washington, have invented certainnew and useful Improvements in Refrigerators, of which the following is a full, clear, and exact description.

Myinvention relates to improvements in refrigerators, and comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation taken on the line 1 1 in Fig. 3. Fig. 2 is a sectional elevation taken at right angles to that of Fig. 1, and Fig. 3 is a sectional plan view taken through the ice-chamber at the upper end of the refrigerator.

The outer casing of my improved refrigerator may be constructed after any ordinary or approved plan. This casing, as herein shown, consists of double walls A and A and is providedwith doors by which ac'cessmay be had to the interior, said doors being placed at any convenient or desired point. As herein shown, a door D is provided in the top of the refrigerator, so that the ice may be inserted in the ice-chamber C, said door, as herein shown, being formed within a larger door D which is of such size as to cover the entire upper end of therefrigerator. A door D is also provided in the front of the refrigerator, giving access to the large storagechamber 1) in the bottom of the refrigerator.

The novel features of my refrigerator are contained within the inner casing. This inner casin g is constructed of metal and is made in two parts, the outer portion B, which fits closely within the wooden box or casing, which is usually placed about a refrigerator, and an inner casing B, which fits within said casing B an d provides air-circulatin g spaces between the two. This inner casing B also forms the main storage-chamber h. The front and rear walls of these two casings B and B are the same, so that the airspaces are restricted to the top and bottom and the two opposite sides.

The upper portion of the refrigerator is divided into three chambers, the central chamdrains from the spouts C 1899 Serial No. 727,806. (No model.)

her 0 being the ice-receiving chamber and the two side or flanking chambers E being storage-chambers. The ice-receiving chamber 0 does not extend entirely across the refrigerator, buta partition is provided which divides of the air-flue F by which the air is conducted from the lower portion of the refrigerator to the top of the ice-chamber. The water formed by the melting ice and the air cooled by contact with the ice are both conducted from the ice-chamber through drains O, which pass through the bottom of the storage-chambers E. These drains C are provided with projections 0 which extend the greater part of the distance across the airlines of spaces F, located at each side of the refrigerator. The outer casing B is provided on its inner surface and beneath the projections or spouts O with a series of pockets G, which form receptacles for the water which These pockets G are constructed so that they overflow into each other, so that the entire series will be filled with water. The upper or overflow edges of these pockets orcups are rolled over and downward, forminglips g, which extend inward a sufficient distance, so that the water dripping'therefrom will fall within the cup next below. This water dripping downward through the air-space through which the air flows as it passes from the ice-chamher to the main storage-chamberwill cool the air and at the same time clear it of impurities.

The air-space E, which is between the bottom of the storage-chamber b and the bottom of the outer casing B, is designed to have a layer of water over it at all times. To secure this result, an overflow-pipe J is inserted through the bottom of the refrigerator and has its inner end projectinga slight distance above the bottom, so that a depth of water corresponding to the projecting portion of this pipe will be retained within the refrigerator at all times. The lower end of this pipe J is provided with a crook or bend adapted to form a water seal and prevent entrance of air.

In order to be able to draw out all the water in the refrigerator when desired, a pipe I is connected with the bottom thereof and is provided at its lower end with a cap it, by

means of which it may be ordinarily closed, but may be opened for drawing off the water when desired.

The air-space F at each side of the refrigerator is continued up alongside of the storage-chambers E and ends withasimilar space F, which extends over the top of said storage-chambers. The end of this upper passage is provided with holes f, by means of which the air may enter the ice-chamber C.

The cold air which passes downward through the passages F enters the passage F,

' which lies beneath the bottom of the storagechamber, and enters said storage-chamber through an opening H in its bottom. This opening is provided with guides 11 at each side thereof and a slide H working in said guides, by means of which the opening may be closed when desired. This slide is connected by means of a link it with the door D, so that when the door is opened the slide is automatically pulled outward and the opening H closed, thus preventing the escape of a large part of the cold air.

This refrigerator is adapted to be used with cold water without using any ice in places where this may be desirable. This is done by inserting a pipe K through the top of the refrigerator and opening into the ice-chamber 0. If a stream of water be allowed to certain of carrying it off, so that it will not rise into the storage-chambers.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a refrigerator, a vertically-extending series of upwardly-extending pockets adapted to receive the drippin gs from the ice-chamber, each. pocket having a downwardly-extending lip adapted to direct the overflow from one pocket to the pocket next below, as set forth.

2. A refrigerator provided with an ice-chamber, and a series of outwardly and upwardly extending pockets on the sides of the refrigerator' below said ice-chamber and adapted to receive the drippings from the latter, the said pockets beinglocated one below the other and each having a downwardly-extending lip whose lower edge lies nearer the side of the refrigerator than the upper and outer end of a the pocket next below, as and for the purpose set forth.

3. A refrigerator having an ice-chamber in its upper part, a series of pockets on the side walls and arranged to overflow intoeach other, the overflow-lip of said pockets being rolled downward and under, so that the water will drip from the lower edge thereof into the pocket below, and means for conducting the water from the ice-chamber into the upper pocket of the series, substantially as described.
